Stitching with the 40/4

The Hartblei 40/4 offers an intriguing advantage for making higher resolution stitched images: a tripod mount which keeps the lens in a fixed position, thus eliminating parallax caused by the lens being moved during a shift (the camera moves instead).

In fact, the Hartblei 40/4 is the only shift lens available today that has a tripod mount. The tripod mount is also a near-necessity, given the weight of the lens (1706g = 3 pounds 12 ounces); stressing the lens mount with the weight of the lens and the torque of shift or tilt isn’t a good idea.

While desirable, the tripod mount has a downside: there is no straightforward way to do a center/left/right stitched image, since the shift mechanism is unidirectional. However, with the lens fixed on the tripod, one can press the rotation-release lever on the lens, which allows the camera to rotate by 180°. The trick is getting 180°, instead of 170° or 185° (or whatever). It’s doable, but far from ideal. Alternative designs which allow left/right bi-directional shifting do not have this issues.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.

Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.

  • Make better images by learning how to get the best results right away.
  • Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
  • Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
  • Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
  • Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
  • Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
  • Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
